Question

What are the exact solutions of x2 + 5x + 2 = 0?

Answer 1

This is quadratic form

Answer 2

You can use the quadratic formula.
If:\[y=ax^2+bx+c\]
\[x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}\]

In this case:
a=1
b=5
c=2

So:
\[x=\frac{-5 \pm \sqrt{5^2-4*2}}{2}=\frac{5 \pm \sqrt{17}}{2}\]

There are two answers for x.
\[x=\frac{5+ \sqrt{17}}{2}\]
\[x=\frac{5- \sqrt{17}}{2}\]

Answer 3

alright thanks for the help
